Green Laser Pointers Features and Applications-TradeTang

TradeTang Introduce the features, applications, advantage and disadvantage of Green Laser Pointer.
Green laser pointer for the first time commercial sales in 2000. They work in the 532 nm wavelength. This wavelength laser diode is not such a big green light, largely by "DPSSFD" the use of laser technology available.

The process:
A very high-power infrared laser diodes in the 808-nm pump of a small piece of Nd: YVO4 crystal, resulting in the 1064 nanometer light work. This diet with potassium interactivity frequency doubling crystal, producing a clear green light wavelength of 532 nm. High power laser pointer green instead of using three lithium borate KTP's.

Features:
An infrared filter, it is entirely behind the mirror, removed from the output beam of infrared spectral radiation. In order to reduce cooling problems and prolong battery life, some green laser pointers working in pulsed or quasi-continuous wave (quasi-continuous) mode. The third type of laser pointer products can make a 5-mW output power. This is the highest law of the streets of laser-driven one. There were even some green laser pointer is 10 MW, including one in the dark within 20,000 feet of output. Some even as these high-power lasers pointers can blind a person 3 seconds delay function. Some laser pointer spread provision. They work with the camera in order to minimize the spread of the laser beam. Since its price from 55 dollars. Majority of them have about 3,000 hours of life.

Application:
Green lasers pointer can be used for a variety of positions. They can be used as a pointing device. Can form a continuous line in the dark, is an additional benefit, which led to the use of light as a rescue, because it can be seen from miles away. It was used as a laser show. It can also be used as a human being can be targeted using a concept of green laser stars of the sky. It also can be used as a pointer laser guns, rifles. Alien vs Predator in the movie it was used as a pointing device of some G36k carbine.

Advantages:
Green laser pointer has many advantages. This is 50 times the red laser, because it can be seen from miles away, the light, which is helping to save a person who is lost. It can also be used in high-tech weapons targeting purposes. Because of its high range, green laser pointer can be equipped with different types of weapons. High temperature does not affect the performance of the green laser pointer case is the one who lost in the desert, he can still use the green laser pointer for help, in other cases, even if a person loses a number of places in all the snow-covered mountain, he can still use it.

Disadvantages:
Because of its high power can permanently damage a person's eyes. Because it can form a light may reveal a person's position, it can not covert action or by the special police used the same strain.

Green laser Pointer is quite terrific, but should be used with caution.
